Patient driven Not all conventional therapies 100% effective Supposedly non-toxic Many tumors are not organ-confined: Holistic Approach What to Look for in Natural Therapies • A known mechanism of action • Evidence that it relieves symptoms • Demonstrated safety • Quality of Product • Low cost • No interaction with other meds Plant-Derived Anticancer Drugs 1881 1958 1959 1960 Podophyllum Catharanthus roseus Ochrosia elliptica Podophyllotoxin Vincristine & Vinblastine Ellipticine 1997 Taxus brevifolia Paclitaxel Anticancer Drugs 1966 Raphanus sativus Olomucine Roscovitine (synthetic) Camptotheca acuminata Camptothecin 1980 1989 Amoora rohituka Flavopiridol (semi-synthetic) 1972 Cephalotaxus harringtonia Combretum caffrum Combretastatin A4 Homoharringtonine Holistic Urology Roles for Supplements • • • • • • • Urinary Tract Infections BPH and Voiding Disturbances PSA elevations Pre-cancerous conditions (PIN) Prostate Cancer Bladder Cancer Sexual Dysfunction 2009 Estimated US Cancer Cases* Men 745,180 Women 692,000 Prostate 25% 26% Breast Lung & bronchus 15% 14% Lung & bronchus Colon & rectum 10% 10% Colon & rectum Urinary bladder 7% 6% Uterine corpus Non-Hodgkin lymphoma 5% 4% Non-Hodgkin lymphoma Melanoma of skin 5% 4% Thyroid Kidney & renal pelvis 4% 4% Melanoma of skin Oral cavity 3% 3% Ovary Leukemia 3% 3% Kidney & renal pelvis Pancreas All Other Sites 3% 3% 20% 23% Leukemia All Other Sites *Exclude s ba sal and squamous cell skin cancers and in situ carcinoma s except urinary bladder.

Target Populations for Prevention in Your Practice • Primary Prevention: • African Americans • Family History • High Grade PIN • Secondary Prevention: • Elevated PSA, Negative biopsy • Post-RRP/Radiation with Rising PSA All Men Over 40 are at Risk!! Prostate Cancer Development • Linked to Inflammation • Many men have prostatitis on biopsy • Cancers linked to Inflammation: • • • • Colon Breast Bladder Thyroid Pathway for Human Prostate Cancer Progression NORMAL EPITHELIUM PROSTATIC INTRAEPITHELIAL NEOPLASIA (PIN) INVASIVE CARCINOMA METASTASIS ANDROGEN INDEPENDENCE Pre-Cancerous Condition ImmunoKinoko AHCC 12 AHCC Production Facility (Sapporo, Japan) 13 Annual Research Symposium 14 AHCC (Active Hexose Correlated Compound) 1. Very low-molecular-weight (5,000Da), highly absorbable alphaglucan-rich compound 2. Produced from enzymatically fermented mycelium of Japanese medicinal mushrooms 3. Clinical shown to have strong immunomodulating properties • Increase NK cell activity • Increase number and activity of DC cells • Increase cytokine response 4. Research • 24 Pubmed-listed studies published in peer-reviewed journals • Numerous other studies published in Japanese journals 5. Clinical Use: in over 1,000 clinics and hospitals, primarily in Asia 1. Primary Care Clinics (immune support and prevention) 2. Cancer Clinics (immunotherapy reduction of chemo side-effects) 3. Hospitals (reduction of hospital borne-infections) 4. Hepatology Clinics (reduce viral loads in Hep-C patients) AHCC and NK Cells • Significantly increases NK cell activity in immune compromised patients • Stimulates T-cells, macrophages and increases cytokines • Increases activity and number of DC cells • Appears to be able to stimulate and modulate because it works on both the macrophages and the cytokines: valuable links and network messengers • Built in dampening system; can be taken continuously and does not need to be stopped like other immune-enhancing supplements AHCC Research: Select Published Animal Studies ▪ Infections: influenza20, west nile virus15, bird flu11, MRSA19 ▪ Tumor necrosis, improved survival of tumor-bearing mice ▪ Reduced side-effects of chemo8 & non-interaction with chemo3 ▪ Anti-inflammatory properties (colitis26; diabetes13) ▪ Auto-immunity (Amyotrophic Lateral Sclerosis (ALS)12) ▪ Protective effect on bone marrow9 , thymus gland7, liver22, spleen8) ▪ Enhanced activity of NK cells, T-cells, macrophages, cytokines AHCC: Select Published Clinical Studies ▪ 269 liver cancer patient prospective cohort study (1992-2001) showed longer “no recurrence” period and increased survival rate (Journal of Hepatology)33 ▪ 132 stomach cancer patients showed enhanced 5-yr survival rate34 ▪ 44 liver cancer patient placebo-controlled study showed prolonged survival and improved Quality of Life36 ▪ 30 healthy elderly patient study at Yale Medical School showed increased cytokine production (TNF-γ and IFN-α) 4 ▪ 20 healthy patient DBPC study showing increased number and activity of dendritic cells (Nutrition and Cancer)5 ▪ Phase-I 26-subject safety study at Faulkner Hospital (9g/day)10 TIME Feb. 23, 2004 Role of NF-kB in Development of Cancer Anti-apoptosis/survival Immortality e.g; bcl-xl, cIAP, survivin, cFLIP, TRAF, SOD, γ-GCS e.g; telomerase Inflammation Proliferation NF-κB TNF, IL-1,Che mokines Angiogenesis e.g; TNF, IL-1, IL-6 CyclinD1, cMyc Tumor promotion VEGF, TNF, IL-1, IL-8 e.g; COX2, iNOS, MMP-9, uPA Metastasis e.g; ICAM-1, VCAM-1, ELAM-1 Aggarwal BB, Cancer Cell, 2004 Zyflamend: Herbal Anti-Inflammatory Turmeric (14.1%) Holy basil (12.8%) Curcumin Ursolic acid Ocimum sanctum Curcuma longa Rosemary (19.2%) Rosmarinic acid, Camphor, Borneol, Cineol Ginger (12.8%) Gingerol Rosmarinus officinalis Zingiber officinalis Green tea (12.8%) Epigallocatechin gallate Huzhang (10.2%) Resveratrol, Thymol Camellia sinensis Polygonum cuspidatum Chinese goldthread (5.1%) Berberine Barberry (5.1%) Berberine Berberis vulgaris Coptis Chinensis Baikal skullcap (2.5%) Baicalin, Baicalein, Wogonin Scutellaria baicalensis Oregano (5.1%) Thymol Origanum vulgare Clinical Trial Administering Zyflamend™ for Prostatic Intraepithelial Neoplasia (PIN) HGPIN (+): Positive NF-kB HGPIN (-): Negative NF-kB Lycopene Found in tomatoes, watermelon, guava and even pink grapefruit ProstaCell contains this antioxidant with highest capacity for scavenging free radicals1 1 Gester.
